+There are a number of good sources for valgrind suppression files:
+
+1) The cockpit project: http://cockpit-project.org
+	Suppression files are in the tools directory:
+	https://github.com/cockpit-project/cockpit/tree/master/tools
+
+2) Johan Dahlin's file for the Gtk stack:
+	https://people.gnome.org/~johan/gtk.suppression
+
+3) Daniel Trebbien's GNOME.supp project:
+	https://github.com/dtrebbien/GNOME.supp
+

+against glib version 2.36.3 and so that is what is included.
